The Classification Problem for Simple Unital Finite Rank Dimension Groups

arXiv:1709.06684

Abstract

The Borel complexity of the isomorphism problem for finite-rank unital simple dimension groups increases with rank. This implies that the isomorphism problems for the corresponding classes of Bratteli diagrams and LDA-groups also increase with rank.
